Whether you call it a huge privacy flaw or just an annoyance, Google Buzz can put the contacts you automatically follow—a.k.a. those you most frequently email or chat—on a public profile page. Here's how to undo that.

Google Blogoscoped's Philipp Lenssen felt he had to avoid following certain Buzz contacts, as he didn't want to expose his social circle to the wider net. He's right—if you have a Google Profile, once you set up Buzz, those you're following, and those following you, are shown on your profile page in a right-hand link list.

Update: This might not apply if you haven't touched much inside Buzz, or haven't set up a Google Profile, or that Profile is set to be hidden from the public. If so, you're mostly in the clear. But keep in mind that, once you post to Buzz, your profile will likely be created, and you'll want to know what's getting put up on the web.

To turn this off, sign into your Google account (via Gmail or elsewhere) and head to your Google profile—that link should work if you're signed in. Look for the two links showing "Following X people" and "X people following me." There's a gray note underneath those numbers, indicating whether they're visible to just you or to everyone.

If they're visible to everyone, hit the "Edit Profile" link on the right-hand edge of the blue bar in the middle of the page, to the right of "About me," "Buzz," and "Contact info." In the third column of options there, there are checkboxes that control privacy features, and one of them is labeled "Display the list of people I'm following and people following me." Un-check that box, and now your list of followers and followees is private—or at least seen only by those you're following, perhaps.

Want Google Buzz gone entirely? Log into Gmail, then look at the bottom of your inbox page for a "Turn off Buzz" link. If you're mainly annoyed at Buzz's constant, um, buzzing, read up on removing Buzz updates from your inbox.
